Multi-Threaded Download with  Asynchronous Writing

ABSTRACT

A system and method are presented for the facilitation of threaded download of software record identifiers and software records. Software record identifiers and software records are stored in separate one-dimensional stacks, which stacks feed a plurality of download threads in a first-in, first-out method. Software records and/or software record identifiers may optionally be written in parallel, or in an asynchronous manner. The total number of threads allowed to a user may optionally be limited to a pre-set number. The speed and efficiency of downloading records is increased through use of all of the cores of multi-cored computing systems to substantively concurrently download several threads. The method further allows a failed download thread to restart from the point at which it failed, rather than beginning again from the origin of the thread, thus ensuring that no software records are duplicated, and that no software records are skipped within a download thread.

FIELD OF THE INVENTION

The present invention relates to a process for the maintenance and update of digitized records. More particularly the present invention relates to a method by which records and record identifiers may be accessed in threaded downloads via an electronic communications network.

BACKGROUND OF THE INVENTION

The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions.

The prior art enables the transfer of large amounts of data across the Internet between databases. The prior art fails, however, to provide optimal systems and methods by which the data may be transferred. Improvements on existing prior art methods for access and transfer processes for data record identifiers and data records is desirable across large sectors of user groups.

There is therefore a long-felt need to provide a method and system that provide increased efficiencies of electronic transfers of data and transfer processes of data and data records.

SUMMARY AND OBJECTS OF THE INVENTION

Towards these objects and other objects that will be made obvious in light of the present disclosure, a system and method are provided to enable the electronic transfer of software records by means of a plurality of download threads.

In a first preferred embodiment of the method of the present invention (hereinafter “the invented method”), a target computing system gains access to a plurality of software record identifiers, and writes the plurality of software record identifiers to a one-dimensional digital stack. A first plurality of record identifiers are subsequently written into a first download thread, and preferably deleted from the digital stack, upon completion of the write from the digital stack to the first download thread. A plurality of software records associated with the first plurality of software record identifiers may subsequently be accessed by means of the first thread. Additionally, the invented method may preferably include newly accessed software record identifiers being written asynchronously, while record identifiers are concurrently being written to a plurality of threads.

In a further preferred embodiment of the invented method, a target computer system accesses a plurality of software record identifiers by means of a first download thread. The plurality of software record identifiers is preferably associated with at least one software record, whereby the software record may be retrieved by means of its associated software record identifier within the download thread. The associated software records may subsequently be stored in a one-dimensional digital record stack, and may be written from the digital record stack into the memory of the target computing system.

The present invention further includes a computing system by which a plurality of software record identifiers may be accessed and means by which the plurality of software record identifiers may be stored in a one-dimensional digital stack. The computing system also preferably comprises means to write the first plurality of record identifiers into the first thread from the one-dimensional digital stack, and means by which the written first plurality of record identifiers may be deleted from the digital stack. The computing system further includes means by which the software records associated with the software record identifiers in the thread may be accessed.

Referring now generally to the Figures, and particularly to FIG. 3, FIG. 3 is a block diagram of the source system 104 of the electronic communications network 100 of FIG. 1, wherein the source server 104 comprises: a central processing unit (“CPU”) 104B; a user input module 104D; a display module 104E; a software bus 104C bi-directionally communicatively coupled with the CPU 104B, the user input module 104D, the display module 104E; the software bus 104C is further bi-directionally coupled with a network interface 104F, enabling communication with alternate computing devices by means of the electronic communications network 100; and a source memory 104G. The source software bus 104C facilitates communications between the above-mentioned components of the source server 104.

The memory 104G of the source server 104 includes a source software operating system OP.SYS 104H. The source software OP.SYS 104H of the source server 104 may be selected from freely available, open source and/or commercially available operating system software, to include but not limited to a LINUX(™) or UNIX(™) or derivative operating system, such as the DEBIAN(™) operating system software as provided by Software in the Public Interest, Inc. of Indianapolis, Ind.; a WINDOWS XP(™), or WINDOWS 8(™) operating system as marketed by Microsoft Corporation of Redmond, Wash.; or the MAC OS X operating system or iPhone G4 OS(™) as marketed by Apple, Inc. of Cupertino, Calif. The source memory 104G further includes the source system software program SW. SRC, a source user input driver UDRV.SRC, a source display driver DIS.SRC, and a source network interface drive NIF.SRC. Within a source database management system 104A (hereinafter “DBMS 104A”) is a source database 104I (hereinafter “source DBS 104I”). The source DBS 104I contains a plurality of software records REC.001, REC.002, REC.003, and REC.N, an exemplary first message MSG.001 to be transmitted from the source system 104 to the target system 102, and an exemplary third message MSG.003 to be transmitted from the source system 104 to the target system 102.

The exemplary source system software program SW.SRC is optionally adapted to enable the source server 104 to (a.) generate messages and communicate with the target system 102, (b.) process communicate with and process messages received from the target system 102, and (c.)

manage the source DBMS 104A to perform, execute and instantiate all elements, aspects and steps as required of the source server 104 to practice the invented method in its various preferred embodiments particularly as outlined in the method of FIG. 6, and accompanying text, in conjunction with one or more of the components described in FIGS. 7A through 10C, including interactions with the target system 102.

Referring now generally to the Figures, and particularly to FIG. 4, FIG. 4 is a flowchart of an aspect of the invented method whereby the target system 102 accesses record identifiers REC.ID.001-REC.ID.N, assigns the record identifiers REC.ID.001-REC.ID.N to threads THREAD.001-THREAD.N, and accesses software records REC.001-REC.N. In step 4.02 the target system 102 determines whether to assign one or more time date stamp boundaries TDS.001-TDS.N to a query sent to the source system 104. When the target system 102 determines in step 4.02 to assign one or more time date stamp boundaries TDS.001-TDS.N to a query sent to the source system 104, the time date stamp boundaries TDS.001-TDS.N are assigned to the query in step 4.04. Alternatively, when the target system determines, in step 4.02, not to assign one or more time date stamp boundaries TDS.001-TDS.N to a query sent to the source system 104, the target system 102 proceeds to step 4.06, wherein the target system 102 transmits a query MSG.002 for software record identifiers REC.ID.001-REC.ID.N, optionally but not necessarily bound by the one or more time date stamp boundaries TDS.001-TDS.N assigned above, to the source system 104. In step 4.08 the target system 102 determines whether one or more record identifiers REC.ID.001-REC.ID.N have been received from the source system 104 by means of a record-identifier-containing message MSG.001. When the target system 102 determines in step 4.08 that one or more record identifiers REC.ID.001-REC.ID.N have not been received from the source system 104, the target system 102 proceeds to step 4.10, wherein alternate processes are executed.

In the alternative, when the target system 102 determines in step 4.08 that one or more record identifiers REC.ID.001-REC.ID.N have been received from the source system 104, the target system 102 stores the received record identifiers REC.ID.001-REC.ID.N in a one-dimensional stack STACK.001-STACK.N, or in a row RW.001-RW.N of a two-dimensional stack STACK2.001-STACK2.N in step 4.12. In step 4.14 the target system 102 determines whether additional record identifiers REC.ID.001-REC.ID.N are present which may be stored in the one-dimensional stack STACK.001-STACK.N. When the target system 102 determines in step 4.12 that additional record identifiers REC.ID.001-REC.ID.N are present or received from the source system 104, the target system 102 returns to step 4.08, and completes the loop of steps 4.08 through 4.12 until a positive determination is reached in step 4.12. When the target system 102 finds that no additional record identifiers REC.ID.001-REC.ID.N are present to be stored in the one-dimensional stack STACK.001-STACK.N, the target system proceeds to step 4.16. In step 4.16, a first counter C1 is initialized, for the purpose counting the number and/or volume of record identifiers REC.ID.001-REC.ID.N assigned to one or more download threads THREAD.001-THREAD.N. The maximum number of record identifiers REC.ID.001-REC.ID.N which may be assigned to the one or more download threads may optionally be determined by a previously designated thread count value Tcv.

In step 4.18 a download thread THREAD.001-THREAD.N is initialized by the target system 102. The initialization of the download thread THREAD.001-THREAD.N may be triggered by one or more occurrences within the target system 102, and may more particularly be triggered by the achievement of a previously designated plurality of record identifiers REC.ID.001-REC.ID.N are stored within the one-dimensional stack STACK.001-STACK.N. In step 4.20 a first plurality of record identifiers REC.ID.001-REC.ID.N are written into the download thread THREAD.001-THREAD.N; the first plurality of record identifiers REC.ID.001-REC.ID.N may optionally be written to the download thread THREAD.001-THREAD.N in a synchronous manner, or may optionally and preferably be written into the download thread THREAD.001-THREAD.N asynchronously. In step 4.22 the plurality of record identifiers REC.ID.001-REC.ID.N which have been written to the download thread THREAD.001-THREAD.N are excluded from the one-dimensional stack STACK.001-STACK.N, optionally and preferably by means of overwriting of memory locations within the target memory 102G of the target system 102. The target system 102 subsequently proceeds to step 4.24, wherein the target system 102 determines whether additional record identifiers REC.ID.001-REC.ID.N are present within the stack STACK.001-STACK.N which may be written to the instant download thread THREAD.001-THREAD.N. When the target system 102 determines in step 4.24 that additional record identifiers REC.ID.001-REC.ID.N are present within the stack STACK.001-STACK.N which may be written to the instant download thread THREAD.001-THREAD.N, the target system 102 proceeds to step 4.26, wherein the target system 102 increments the first counter C1. In optional step 4.28 the target system 102 optionally determines whether the instant thread THREAD.001-THREAD.N has reached a previously determined maximum number of record identifiers REC.ID.001-REC.ID.N. When the target system 102 determines in step 4.28 that instant thread THREAD.001-THREAD.N has reached a previously determined maximum number of record identifiers REC.ID.001-REC.ID.N, the target system 102 proceeds to step 4.18, wherein a new download thread THREAD.001-THREAD.N is initialized. Alternatively, when the target system 102 determines in step 4.28 that the instant download thread THREAD.001-THREAD.N has not reached a previously determined maximum number of record identifiers REC.ID.001-REC.ID.N, the target system 102 proceeds to step 4.20, and writes an additional plurality of record identifiers REC.ID.001-REC.ID.N into the download thread THREAD.001-THREAD.N. In the alternative, when the target system 102 determines in step 4.24 that there are no additional record identifiers REC.ID.001-REC.ID.N in the one-dimensional stack STACK.001-STACK.N, the target system 102 requests access to the software records REC.001-REC.N associated with the record identifiers REC.ID.001-REC.ID.N in a designated download thread THREAD.001-THREAD.N in step 4.30. In optional step 4.32, the accessed records REC.001-REC.N associated with the record identifiers REC.ID.001-REC.ID.N in the designated download thread THREAD.001-THREAD.N are written into the target database 1021 in the memory 102G of the target system 102. The target system 102 subsequently returns to step 4.08, wherein it is determined whether one or more record identifiers REC.ID.001-REC.ID.N have been received.

Referring now generally to the Figures, and particularly to FIG. 5, FIG. 5 is a flowchart of an aspect of the invented method whereby the target system 102 accesses record identifiers REC.ID.001-REC.ID.N from threads THREAD.001-THREAD.N, accesses a plurality of software records REC.001-REC.N associated with the record identifiers REC.ID.001-REC.ID.N, and writes the records REC.001-REC.N associated with the record identifiers REC.ID.001-REC.ID.N into a record stack REC.STACK.001-REC.STACK.N in the memory 102G of the target computing system 102.

In optional step 5.02 the target system 102 optionally assigns one or more time date stamp bounds TDS.001-TDS.N for the download thread THREAD.001-THREAD.N that the target system 102 will access. In step 5.04 the target system 102 accesses the desired thread THREAD.001-THREAD.N, and in step 5.06 the target system 102 accesses the record identifiers REC.ID.001-REC.ID.N within the desired thread THREAD.001-THREAD.N. In step 5.08 the target system 102 determines whether the record identifiers REC.ID.001-REC.ID.N accessed in step 5.06 are associated with software records REC.001-REC.N. When the target system 102 determines in step 5.08 that the record identifiers REC.ID.001-REC.ID.N accessed in step 5.06 are not associated with software records REC.001-REC.N, the target system 102 executes alternate operations in step 5.22. Alternatively, when the target system 102 determines in step 5.08 that the record identifiers REC.ID.001-REC.ID.N accessed in step 5.06 are associated with software records REC.001-REC.N, the target system 102 proceeds to step 5.10.

In step 5.10, the target system 102 determines whether additional record identifiers REC.ID.001-REC.ID.N remain to be accessed. When the target system 102 determines that additional record identifiers REC.ID.001-REC.ID.N remain to be accessed, the target system 102 proceeds to step 5.06, and accesses the additional record identifiers REC.ID.001-REC.ID.N. Alternatively, when the target system 102 determines that no additional record identifiers REC.ID.001-REC.ID.N are present to be accessed, the target system 102 proceeds to step 5.12, wherein the target system 102 requests access to the one or more software records REC.001-REC.N associated with the accessed record identifiers REC.ID.001-REC.ID.N. The target system 102 may preferably and optionally request the one or more software records REC.001-REC.N associated with the accessed record identifiers REC.ID.001-REC.ID.N from the source system across the network 100. In step 5.14, the target system 102 receives the one or more records REC.001-REC.N and stores the one or more records REC.001-REC.N in the record stack REC.STACK.001-REC.STACK.N. In step 5.16, the target system 102 writes the one or more records REC.001-REC.N to the memory 102G of the target computing system 102.

In step 5.18 the target system 102 determines whether additional software records REC.001-REC.N remain in the record stack REC.STACK.001-REC.STACK.N to be transferred to the memory 102G of the target system 102. When the target system 102 determines that additional software records REC.001-REC.N remain in the record stack REC.STACK.001-REC.STACK.N to be transferred to the memory 102G of the target computing system 102, the target system 102 proceeds to step 5.14, and executes the loop of steps 5.14 through 5.18 as necessary.

Alternatively, when the target system 102 determines in step 5.18 that no additional software records REC.001-REC.N remain in the record stack REC.STACK.001-REC.STACK.N to be transferred to the memory 102G of the target computing system 102, the target system 102 proceeds to step 5.20. In step 5.20 the target system 102 determines whether to terminate the process. When the target system 102 determines not to terminate the process, the target system 102 proceeds to step 5.04 and re-executes the loop of steps 5.04 through 5.20 until a positive determination is achieved in step 5.20. When the target system 102 determines in step 5.20 to terminate the process, the target system 102 executes alternate operations in step 5.22.

Referring now generally to the Figures, and particularly to FIG. 6, FIG. 6 is a flowchart of an aspect of the invented method whereby the source system 104 is queried and accessed for record identifiers REC.ID.001-REC.ID.N and software records REC.001-REC.N. In step 6.02 the source system 104 determines whether a request for record identifiers REC.ID.001-REC.ID.N has been received from the target system 102. When the source system 104 determines in step 6.02 that a request for record identifiers REC.ID.001-REC.ID.N has been received from the target system 102, the source system 104 transmits the record identifiers REC.ID.001-REC.ID.N to the target system 104 in step 6.04. Alternatively, when the source system 104 determines that no request for record identifiers REC.ID.001-REC.ID.N has been received from the target system 102, the source system 104 proceeds to step 6.06. In step 6.06, the source system 104 determines whether a request for software records REC.001-REC.N has been received from the target system 102. When the source system 104 determines in step 6.06 that a request has been received from the target system 102 for software records REC.001-REC.N, the source system 104 transmits the software records REC.001-REC.N to the target system 102 in step 6.08. When the source system 104 determines in step 6.06 that no request has been received from the target system 102 for software records REC.001-REC.N, the source system 104 executes alternate operations in step 6.12. In step 6.10 the source system 104 determines whether any outstanding or additional requests are present. When the source system 104 determines that there are outstanding and/or additional requests, the source system 104 re-executes the loop of 6.02 through 6.10. When the source system 104 determines that no outstanding or additional requests are present, however, the source system 104 executes alternate processes.
